girlfriend
The Italian word 'fidanzata' is used to refer to a female partner in a romantic relationship. It is often used interchangeably with 'ragazza' (girl), but 'fidanzata' implies a more serious and committed relationship. It's also important to note that in Italian, the word 'fidanzata' can also refer to a woman who is engaged to be married, equivalent to the English 'fiancée'.
